WINDOWS SERVER 2003、IIS6、ASP.NET2.0,用微软的UrlRewriter组件重写URL
一、配置IIS6在IIS下配置“应用程序映射”,也就是对于不同的扩展名(.php、.html、.asp、.aspx等)都有谁来处理
这里我们选择“通配符应用程序映射”,也就是把所有扩展名,包括没有扩展名的,或者以/结尾的url,都发送到ASP.NET来处理。
ASP.NET处理这些文件的程序,也就是“可执行文件”是:C:/WINDOWS/Microsoft.NET/Framework/v2.0.50727/aspnet_isapi.dll,这个文件。
确认文件是否存在不要选,因为url重写后很多情况都是没有对应文件的。
二、在自己的网站中引用微软的UrlRewriter组件
微软的URL重写类在这里下载,下载后只需编译里面的URLRewriter类为DLL文件,然后在你的项目中做个引用就可以了。

三、在网站的web.config文件里注册UrlRewriter组件并添加改写规则
<configSections><section name="RewriterConfig" type="URLRewriter.Config.RewriterConfigSerializerSectionHandler, URLRewriter" /></configSections><system.web><httpModules><add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/><!-- 用于 URL 重写 --><add type="URLRewriter.ModuleRewriter, URLRewriter" name="ModuleRewriter" /><!-- 用于 URL 重写 --></httpModules></system.web>
web.config里面有两部分配置用于注册UrlRewriter,一部分在 configSections 里面,一部分在 System.Web 里面
然后就是在 web.config 里面配置重写规则,可以用正则表达式来匹配改写后的url,发现匹配(lookfor)后,转到(SendTo)原始url
<RewriterConfig><Rules><RewriterRule><LookFor>(.+)/(.+).html</LookFor><SendTo>~/$2.aspx</SendTo></RewriterRule><RewriterRule><LookFor>~/(/d{4})/(/d{2})/(/d{2})/.aspx</LookFor><SendTo>~/ShowBlogContent.aspx?year=$1&month=$2&day=$3</SendTo></RewriterRule></Rules></RewriterConfig>
四、处理回发
访问一个被重写了的url,而这个url上面有一个窗体,虽然打开窗体的时候,使用的是重写前的url,但是当点击窗体的提交按钮的时候,窗体会被定向到重写后的实际的url去。
具体的实现方法就是“利用ASP.NET 2.0控件适配器扩展架构来定制控件的输出”,说白了就是ASP.NET 2.0提供了一个功能,可以手工的改写服务器控件。那么我们可以改写form控件的窗体的action,也就是提交路径的属性。
需要两个文件:
1、
App_Browsers/Form.browser<browsers><browser refID= "Default" ><controlAdapters><adapter controlType= "System.Web.UI.HtmlControls.HtmlForm"adapterType= "FormRewriterControlAdapter"/></controlAdapters></browser></browsers>
App_Code/FormRewriter.csusingSystem.Data;usingSystem.Configuration;usingSystem.Web;usingSystem.Web.Security;usingSystem.Web.UI;usingSystem.Web.UI.WebControls;usingSystem.Web.UI.WebControls.WebParts;usingSystem.Web.UI.HtmlControls;/// <summary>/// FormRewriter 的摘要说明/// </summary>public classFormRewriterControlAdapter : System.Web.UI.Adapters.ControlAdapter{publicFormRewriterControlAdapter(){}protected override voidRender(HtmlTextWriter writer){base .Render( newRewriteFormHtmlTextWriter(writer));}}public classRewriteFormHtmlTextWriter : HtmlTextWriter{publicRewriteFormHtmlTextWriter(HtmlTextWriter writer):base (writer){base .InnerWriter = writer.InnerWriter;}publicRewriteFormHtmlTextWriter(System.IO.TextWriter writer):base (writer){base .InnerWriter = writer;}public override voidWriteAttribute( stringname,stringvalue,boolfEncode){//If the attribute we are writing is the "action" attribute, and we are not on a sub-control, //then replace the value to write with the raw URL of the request - which ensures that we'll//preserve the PathInfo value on postback scenarios if(name =="action" ){HttpContext context = HttpContext.Current;if(context.Items[ "ActionAlreadyWritten" ] ==null ){//We will use the Request.RawUrl property within ASP.NET to retrieve the origional //URL before it was re-written. value = context.Request.RawUrl;//Indicate that we've already rewritten the <form>'s action attribute to prevent//us from rewriting a sub-control under the <form> controlcontext.Items[ "ActionAlreadyWritten" ] =true ;}}base .WriteAttribute(name, value, fEncode);}}
URL重写就可以在 Windows Server 2003 + IIS6 + ASP.NET 2.0 下实现了
